(was: Hi [~fmcquillan] ,

In case of grouping in Personalized Page Rank, what if :
 # The nodes of interest are not present in the group?
 # Or only a subset of nodes of interest is present in the group. What will be 
the initial probability in this case?

 

For eg: 

special nodes = 2, 3

Initial probability = 1 / number of special nodes = .5 for each special node

Random Prob = 1 - .85 = .15 for each special node. 

{code}
| |special nodes = 2, 3| |
|Group 1|nodes|initial prob|random prob|
| |1|0|0|
| |2|0.5|0.15|
| |3|0.5|0.15|
| |4|0|0|
| |5|0|0|
| |6|0|0|
| | | | |
|Group 2| | | |
| |3|0.5 or 1?|0.15|
| |4|0|0|
| |5|0|0|

{code})
